Every business with a competent marketing department will continuously track and measure the effect of the ads they run, like how many users who click the ads turn into paying users.
My startup has tried a variety of marketing strategies from in-person campaigns on the street, video ads on YouTube, "free" PR through newspapers etc. In order to measure the effect of each approach we only did one at a time.
For us paid marketing on Facebook/Instagram was, unexpectedly, the most efficient form of marketing by far. But I would not assume that applies to all, or even most, businesses. So you should experiment with different strategies for your business.
It's the tracking part here that's hard. How do you know that the FB/IG ad was the first time the converting user heard of your product, or that it was the deciding factor? If you literally have no other way of discovering your product than this works, but it's easy for FB/IG to show your ad to users who were already going to convert and claim the conversion...
I see this so many times. Someone Googles for <product name> and then clicks on the ad for said product instead of their website which is the first organic result. Google claims it’s an ad conversion and gets the money, marketing monkey will happily take this as credit for their work and justification for further ad spend & their own salary, while the truth is that this user already made their decision to use this product (as they’ve searched for it) and didn’t need the ad.
I dislike ads in general. Specially Youtube ads. They are hysterical and for some god knows reason advertisers think its a good idea to repeat ad nauseum the same ad multiple times even on the same video. I end up hating the brand more than having some interest in the product.
(Paid) reviews on the other hand like unboxing, configuring and testing a product that I'm interested in are totally another thing. This applies to furnitures, house appliances, computers and so on. A good example is that I did not knew how much I wanted to build a fully silent computer before watching so many build videos of a certain fanless case that looks like a metal cube.
